.. Supposedly, allows one to dwell 'side-by-side' with other dimensions, {& dimensional beings}; Yet, because of their 'higher' vibrational-frequency; Our awareness factor of them, is no more tangible, than mostly, second-hand ghost, and-or, poltergeist, accounts.
 
Possible analogies, are that, one can't 'see' the blades, of a rapidly rotating fan; Which, obviously; Doesn't annul their reality, while rapidly rotating. -- Or, for that matter; The {vibrational}, electrical frequencies, of radio & 'TV' stations; Co-exist, side-by-side, in our atmosphere. Yet, without a 'tuner'; One might never guess, that there are multiple, coherent signals; That, when received without benefit of the {tuner} filtering process; Is merely, an incoherent reception, of 'white noise.' --
